To all whom 'it may concern:

ie it known that I, GEORGE G. Sensori-DER,

a citizen of the United States, residing .at Washington, in the District or" 'Columbia,

have invented certain new and useful Improvements in Rotary EXplosiveEngines, of which the following is a specification.

This inventionrelates to certain new and useful improvements' in explosive engines and pertains more particularly to that type of rotary engines operated by the' impactJ from explosive gases.-

.The invention has for its object theproduction of a simple and inexpensive engine adapted particulirly for the. use of denaturedv alcohol as an explosive and in which pressed prior the explosivek gases are automatically comto the explosion thereof, although I do not desire to limit myself t'o any particular hydrocarbon fluid.

A further object is to produce an improved pistonconstruoted to resist the lateral force of' the explosive impact. A further object is to provide a gas tight cylinder in which the parts will not bind when expanded under theheat generated by the explosions. f

A further object is to provide means for cooling thev cylinder and piston.

The invention will be vFig. 2 is a longitudinal `sectional v'ievv or" the.

engine in avertical -position, parts .being-v sition and provided shown in elevation. lar'to Fig. 2, and illustrating a slight modification., Fig. 4 is a longitudinal sectional` view the section being taken at right angles Aa side view,j one end head being removed. Fig. 6 isa sectional View illustrating a slight modification.

Referring to the draivirig, 10 designates the cylinder or casing provided Wit-h a cylindrical extensionv 11 removably secured theretoin-anv referred manner. The casing 10 is cylindrical in cross section and provided with` end heads 12 removably secured in powith bosses 13 'which the shaft 14 onf which issecured the piston Said piston is also cylindrical in contour to conform to "the can serve as bearings for ft ie guides 20 with packing rings 28.

' In Fig. 6 Ihave il hereinafter fully .Seli Otll 'lld particularly Pointed out inthe I the cylinder` and' ber 3 4 normally closed by Fig. 3 is a vietriT 'sii/nim tour of the casing 10 and has its periphery channeled out io'torin anpexplosion chamber 16 the bottom 17 of which is curved in- Wardly on an eccentric line leading infrom the 'point 18 of ,the said periphery and termi-- nating in a perpendicular impaet'iace 19.

The piston` 15 is mounted to rotate between guides"-f0 which. are concentric with the cylinder and provided with ainiular flanges forming outer chambers .21. Said guides are free to move longitudinally oi' the shaft 14 and 'are normally held in contact with the ends ofthe piston by means of con- -caved spring disks 22, 2.3 each mounted on the shaft-14 andheld in position by adjustable collars .24, 24. Each of said disks is Vsplit radially to form arms 25, antifriction ,rollers 26 beingrnountedin the free ends of said varrns at the; point of vcontact with the piston. Saidv collars 24 also serve to resist the 'end thrustof shaft14. In orderto prevent leakage 'around the several parts, the piston is provided with packing rings Q7 and A reciprocating abutment 29 isy arranged in a radial chamber 3U, being normally projected into the explosion chamber by a spring 31 lust-rated the guides :2O as held in position byCoil spring 22.

The extension 4'11"is rovided with a cylindrical bore 32 .tap ered ,at the end adjacent communicating ivith the explosion Achamber .16. Within the cylindrical portion of emensionll is mounted al .piston 33 provided With-an interior chama valve 35. Said valve is provided with agstem 36 passed down through the hollonv stem 37 of the piston 33, and is held normally to its seat. by a spring` 38. E The piston 33 is reciprocated byineans of a cross head 39 supported by linlrs-flOgslotted at' 41 to receive shaft 14 'and each provided with a pin 42 Working in the grooveof a can; 43 seouredto said shaft. `The charge is ,fed to the interior of extension 11 through' conduits 44, 45,' each provided* V'With a suitable check valve 46'. In order to regulate the operation of valve .35 provide .portion of the pisiion opposite chamber .16.

provide the packing ring 5l, which may be of any preferred construction. I have found, however, that the split ring illustrated is very eflicacious, the top edge thereof projecting beyond the plane of exten- 'sion l1.

Where it is desired to cool the engine I provide casing 10 with a Water jacket 52 provided With inlet and outlet conduits 53, 54 and I also lill the interior of`piston l5 with vvater through an inlet conduit-55 formed in shaft 14 and having a portf-G registering With a corresponding opening in the hub of the piston. An outlet port 56 is arranged to register with an independent outlet conduit 55 whereby circulation is maintained.

i The exhaust for the-engine is illustrated at 57.

In operation, the charge is ignited by any suitable ignition device (not shown), and

. the impact of the explosion acting on the face 19 serves to impelythe piston l5, the piston 33 being immediately lowered. The valve 35 is unseated by projection 48, permitting the explosive mixture below said piston to enter the compression chamber above the same. The return movement o'f the piston compresses the charge, the maximum compression being `reached just as the impact face 19 passes the opening in the end of the compression chamber. At this moment the charge is ignited and the cycle of operation is repeated. l

The advantages of my improved explosive engine Will be readily apparent from 'the foregoing. It Will be articularly noted that the lateral Walls of tlie explosion chamber being integral with the piston, displace ment of the parts due,` to the im act of the explosion is impossible. It Wlll also be noted that by means of the guides and spring disks the cylinder is' rendered gas tight and yet said guides Will automatically accommodate themselves to any expansion or contraction of the piston. It Will be further observed that I have provided simple and eiiicient means for feedingand compressing the explosive gases.
